As Per IS 2386 (P-I)
Aggregates which are flaky and/or elongated will often lower the work ability of a concrete mix and may also affect long term durability. In bituminous mixtures, flaky aggregates make for a harsh mix and may also crack and break up during compacting by rolling. The flakiness of aggregate is determined by measuring the thickness of individual particles. Hence we offer thickness gauge and length gauge to check flakiness and elongation index of the aggregate respectively.
|Elongation Gauge SL-AG-002||Used for determination of elongation index of aggregates. It consists of a steel frame having slots of different dimensions. The frame is fixed on a hard wooden base.|
